MATHEW SHAW, OF LAWRENCE, KANSAS.

IMPROVEMENT IN REFRIGERATORS.

Specification forming part of Letters Patent No. 139,428, dated May 27, 1873; application filed March 25, 1873.

lo all whom it may concern:

` Be it known that I, MATHEW SHAW, of Lawrence, in the county of Douglas and in the State of Kansas, have invented certain new and useful Improvements in Refrigerator; and do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon making a part of this specification.

The nature of my invention consists in the construction and arran gement of a refrigerator, as will be hereinafter more fully set forth.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe its construction and operation, referring to the annexed drawing, in which- Figure l is a perspective view, and Fig. 2

\ a longitudinal vertical section, of my refrigerator. Figs. 3 and 4 are transverse vertical sections through the top part of the same.

A A represent the walls, B the bottom, and C the lid, of my refrigerator, these parts being constructed in any of the known and usual ways, the Walls and bottom being made double, with suitable non-conducting packing. D D represent the provision-chamber, and E the ice-chamber. The ice-chamber E is made of galvanized iron, suspended in such a manner that it will hang clear of the walls'of the refrigerator, and is covered with a hinged lid, G, so as to make it air-tight, thereby securing the full benefit of the ice. The bottom of the ice-chamber being inclined carries oi` all sweat and drip to a gutter, H, with conductor I, which leads through the bottom of the refrigerator, and is at its lower end provided with a cup, J, to make it air-tight. K is a partition, made of galvanized iron, and extending to the bottom shelf of the refrigerator. The provision-chamber is also provided with a lid, G', and between the lids G G and the main lid C is an air-chamber, a, as shown. b b are p ues, leading from the upper partof the provision-chamber to the air-chamber a, to allow the warm and foul air to pass up'and escape through openings'i i in the main lid C. There is a thorough draft from the ice downward, and then up to the chamber a, carrying all foul air in its course, leaving the refrigerator perfectly pure.`

Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is

The arrangement of the tlues or passages b b within the walls of a refrigerator, connecting the interior of the same with the chamber a between the lids, in combination with the outlFebruary, 1873.
